Javascript and Jquery - IE blocking it running (Galleria) - javascript

I have linked to the Jquery library at google in my header, and my local copy of the Galleria Javascript file - as the instructions on the Galleria website said to do.
The code functions perfectly in Chrome. However, when attempting to view the site in IE9 I am faced with "Internet Explorer restricted this webpage from running scripts or ActiveX controls." This is preventing (without user input) the Javascript/Jquery/Galleria stuff to function; it is also prevented an embedded Youtube video from displaying.
What am I missing - plenty of other websites use these functions and I don't get IE giving this message. What do I need to add or change?
I am viewing the website from my PC - it is stored locally at the moment.
Cheers!

This is happening because you are running your website locally. You can be sure that this will not happen once you upload it to a webserver.
You can also run a local webserver. I can recommend WAMP:

Can't print a flash application within electron

My problem
I am currently developing an electron (v4.2.10, I can't upgrade) application with the primary purpose of browsing on a specific homepage (using electron-navigation) and making their flash games playable.
I have included the Pepper Flashplayer (v32.0.0.156) for this purpose and so far it is all working well.
However when trying to print a page including a flash game it will print a blank page. Trying the same in my current versions of Chrome or Firefox (with current flash player) yields the same result, however in Edge it works.
What I've tried so far
I have no access to the actual pages of the site or any of the swf files
The pages with the swf files are http (I tried setting browserWindow web preference disableWebSecurity to true, no change)
I have tried different versions of the flashplayer
Screenshotting the page is sadly not an option
I have looked into the plugin nw-flash-trust but I am accessing an external source
When I downgraded electron to v3.0 it actually managed to print most of the display, which may point to it being related to the underlying chromium version
Does anyone have an idea how I can fix this? I have absolutely no knowledge of flash development itself. I would love to be able to print on v4.10 too. Many thanks for any help!

Spring: open word/excel in the browser

I'm developping a web server based on SpringFramework 4 and I hope to return some files and open them directly in the browser.
So far, I succeed to treat PDF by using Header Content-disposition: inline. But it is not working for word/excel. Google Chrome proposes to download the later or download/open by application.
So I hope to know
whether or not it's possible to open them directly in the browser
if yes, how to do that
As far as i know there is no built in Excel viewer for most browsers (IE is different because it is part of Windows, and so is Office). PDF is a different story ... there are loads of plug-ins available.
You might want to consider opening it in google docs, or office.com.
Apparently, there is a plugin available for firefox ... http://www.microsoft.com/en-gb/download/details.aspx?id=27106
BUT that does mean any users will have to have it installed for them to get the behaviour you want!

Javascript disabled for local network, but not internet

I have run into a bizarre situation on a single computer in my office. All other computers work as they should.
What happens is web pages hosted on the internal server (local network: 192.168.1.6) will not execute any of the javascript functionality on the internal web application. Meaning the buttons, jquery and ajax functionality do nothing.
All 3 browsers on this single computer do not have any javascript functionality: not IE, not Firefox, not Chrome. They just do nothing when you click things.
I have tried uninstalling Firefox and reinstalling ... no change.
Web pages on the internet (such as Gmail or google) work just fine.
We have also tried turning off the virus protection (EmsiSoft) but to no avail.
Does anybody have any ideas short of wiping the machine? Is this a virus? Is it a "feature" of EmsiSoft?

Same Javascript code but not same act

//Edit
Hello.
I have made a website and uploaded to the host. So, the codes what are in my localhost and in the website host are same. Everything works except one JavaScript(jQuery) action(A dropdown menu). On my localhost it works perfect, on the website host, it drops and rises again and than doesn't drop again.
site : http://www.hastahakki.com/index.php?page=anasayfa
The problem on the big buttons like "Doğru Hastane Seçimi" , "Hasta Şikayetleri"
How do I do?
It's rare for pure client code to work differently in a hosted environment provided it is uploaded properly and the same browser is used.
First I would check it's not a cache issue by clearing my browser cache.
Then I would view it in a browser with modern developer tools, which is most browsers with the latest version (Firefox requires the excellent Firebug plugin). In Chrome for instance, looking at the Network output will show you if any resources are failing to load, and the Scripts view will show you any local JavaScript errors that might be triggered by the hosted version.

How do I check in Firefox and Chrome if a plugin is installed

I'm using an embedded plugin in my web app to enable scanning (Dynamsoft's webscanning plugin). I'm serving an xpi to firefox users and a crx to chrome users. When viewing the page without the plugin installed, Firefox will try to download the plugin and the user will need to click "manual install" to install it. Chrome will make no attempt to donwload the plugin (this is by design, according to http://code.google.com/p/chromium/issues/detail?id=15745)
I would like to use javascript to detect wether the plugin is installed or not (preferrably before trying to load it through the embed tag). If no plugin is installed, I want to provide an explanation and a link to the correct plugin to the user. Both browsers install their respective plugins without any problem if the user clicks at a download link instead of just trying to load through the embed tag.
So, does anybody know a way detect wether a plugin is installed using javascript?
Have you had a look at window.navigator.plugins?
..and the equivalent reference for webkit plugins-
The Apple reference for the WebKit DOM appears to have disappeared. navigator.plugins does work for me in Safari & Chrome. See a jsfiddle here: http://jsfiddle.net/2EaKD/
Sounds to me like a potential security hole, if a website (something remotely) could access your plug-ins (something locally). So I guess this is not possible.
Your addon can monitor which pages are opened by the user. If it is your page, you can make your addon set a global variable in that page and your page's JavaScript should be able to detect this.
